This should probably account for the fact that I send international coins inactive and fund them later so they don't have value in customs. Zero balance should mean the balance was successfully stolen, or a convincing fake. On the series 1, someone could erase the firstbits with solvent and print something else, leading you to the wrong address on block explorer. But the 1BTC would still be intact at the original address and this would not be a compromise.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable. I never believe them. If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins. I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion. Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice. Don't keep coins online. Use paper wallets instead.

I have faith this won't cost me anything. If you're robbed or come across a bad employee, this could help track that person down.

good judgment comes from experience, and experience comes from bad judgment
